proceed to the next section, "Installing Windows NT Networking for the 
First Time." Otherwise, follow the steps here to reinstall Windows NT 
networking.

    Reinstalling Windows NT Networking
    ----------------------------------

ADVANCED INTALLATION OPTIONS
----------------------------

    Running Windows NT on a Non-DOS Processor
    -----------------------------------------

    If your system cannot run the DOS-based Configuration and Diagnostic 
    program, you may need to set the speed and duplex level of the NIC in 
    the Windows NT registry.  The speed and duplex value of the NIC can be 
    set manually by using the MEDIA keyword.  To set the MEDIA keyword, add 
    the key MEDIA to the registry in the subkey:    
                    
    \\HKEY_lOCAL_NACHINE\SYSTEM\CurrentControlSet\Services\El90x?\Parameters

    NOTE: Multiple subkeys that look like El90x appear right next to 
          each other.  The correct one has a digit in place of the ? 
          in the above expression to represent which NIC it is.  The 
          incorrect one simply reads El90x.


    The value for the MEDIA keyword should be one from the list below.  The 
    default is NotPresent.  
 
        MEDIA   10HALF     <-- 10 Mbps with half duplex
        MEDIA   10FULL     <-- 10 Mbps with full duplex
        MEDIA   100HALF    <-- 100 Mbps with half duplex
        MEDIA   100FULL    <-- 100 Mbps with full duplex
        MEDIA   AUTO       <-- Driver performs auto configuration
        MEDIA   NotPresent <-- Use settings on EPROM
